Greenhouse Gases (GHGs) are gases in the Earth’s atmosphere that trap heat, contributing to the greenhouse effect and global warming. They allow sunlight to enter the atmosphere freely but prevent some of the heat from escaping back into space, leading to an increase in global temperatures. These gases can be naturally occurring or anthropogenic (human-made).
Impacts:
GHGs are the primary drivers of climate change. Their increasing concentrations in the atmosphere contribute to rising global temperatures, melting ice caps, sea-level rise, and extreme weather events.
Reduction Efforts:
International agreements like the Paris Agreement aim to limit GHG emissions by promoting renewable energy, improving energy efficiency, and adopting sustainable practices in agriculture, industry, and transport.
